Polarity Reversing Rectifier

A Polarity Reversing Rectifier (PRR) na'urar samar da wutar lantarki ce ta DC wacce za ta iya canza polarity na fitarwa. Wannan ya sa ya zama da amfani musamman a cikin matakai kamar electroplating, electrolysis, electromagnetic braking, da kuma sarrafa motar DC, inda canza shugabanci na yanzu ya zama dole.

1.Yadda Yake Aiki
Masu gyara na yau da kullun suna canza AC zuwa DC tare da tsayayyen polarity. PRRs suna ginawa akan wannan ta amfani da na'urorin wuta masu iya sarrafawa-kamar thyristors, IGBTs, ko MOSFETs-don juyar da kwararar na yanzu. Ta hanyar daidaita kusurwar harbe-harbe ko juzu'i na sauyawa, na'urar zata iya jujjuya fitowar a hankali ko da sauri daga tabbatacce zuwa mara kyau.

2.Tsarin Da'irar
Yawanci, PRR yana amfani da cikakken sarrafa gada mai gyarawa:
Shigar AC → Gadar Mai Gyaran Wuta → Tace → Load
Gadar tana da abubuwa guda huɗu masu iya sarrafawa. Ta hanyar sarrafa waɗanne na'urori suke gudanarwa da kuma lokacin, fitarwa na iya canzawa tsakanin:
▪ Kyawawan polarity: halin yanzu yana gudana daga madaidaicin tasha zuwa kaya.
▪ Mara kyau polarity: halin yanzu yana gudana a kishiyar shugabanci.
Hakanan za'a iya daidaita matakan ƙarfin lantarki ta hanyar canza kusurwar faɗakarwa (α), yana ba da damar daidaitaccen iko na duka polarity da girma.

3.Aikace-aikace
(1) Electroplating & Electrolysis
Wasu matakai suna buƙatar halin yanzu don juyawa lokaci-lokaci don haɓaka ingancin sutura. PRRs suna ba da abin sarrafawa, wadatar DC bidirectional don biyan wannan buƙatu.
(2) Kula da Motoci na DC
Ana amfani da shi don aikin gaba / baya da kuma birki na farfadowa, dawo da makamashi zuwa tsarin.
(3)Electromagnetic birki
Juya halin yanzu yana ba da damar birki cikin sauri ko sakin tsarin inji.
(4)Laboratory & Gwaji
PRRs suna ba da fitarwar DC na bipolar mai shirye-shirye, manufa don bincike, gwaji, da gwaje-gwajen da ke buƙatar sassauƙan polarity.

Masu gyara masu jujjuyawar polarity suna ƙara zama mahimmanci a masana'antu da bincike. Suna haɗa ikon sarrafa polarity mai sassauƙa tare da ingantaccen canjin makamashi, yana mai da su mahimmanci ga yawancin aikace-aikacen lantarki na zamani. Kamar yadda na'ura da fasahar sarrafawa ke haɓaka, ana tsammanin PRRs za su sami amfani mai fa'ida.
